When performing WRITE or REWRITE operations on line sequential or line advancing files, the 
                  		INSERTNULL option determines whether to insert NULL (x"00") characters before non-printable characters. The option also determines whether
                  to strip out those NULL characters during READ operations.

Comments:
INSERTNULL takes precedence over the N run-time switch.
If you do not set INSERTNULL, the setting of the N run-time switch determines whether or not NULL characters are inserted before non-printable characters.
